Abstract

Selon cette invention, un métal résistant à la corrosion, tel que le platine ou le MCrAlY, est collé sur un métal sensible à la corrosion (11), tel que les superalliages à base de nickel, de manière à recouvrir sa surface avec les particules (14) du métal résistant à la corrosion maintenues à la surface grâce à un liant (13) recouvert d'une bande de production de métalide (15). Le tout est ensuite chauffé afin d'induire la formation du revêtement de métalide sur la surface du métal, qui, à son tour, colle le métal résistant à la corrosion sur la dite surface.
